The Food Standards Agency is calling for snack food packs to feature more health information about the products. The health White Paper recommends the trial of a traffic light system, with a red light indicating fatty, salty or sugary foods, to be eaten sparingly. Amber would mean fatty but nutritious food, to be eaten in moderation. Green is for fruit and vegetables, to be eaten often. A traffic light system has been introduced by the Co-op and Tesco is testing out its own version, designed by Rocket.

Andy Knowles, a partner at design consultancy Jones Knowles Ritchie, says: ‘Packaging has to give confidence to parents in the light of the current issues. What may change is stuff that single-mindedly attracts kids.’

Knowles thinks the most important factor for designers is that they create packaging that inspires confidence among parents. He says of his own group’s redesign of Penguin biscuits, ‘We wanted to make it clearly identifiable as a Penguin. You have to give it a feel so it doesn’t look artificial or cheap so mothers can be confident about it.’

One way to target both parent and child is through multipacks. Bruce Duckworth, creative director of Turner Duckworth, says the packs are bought by mothers for their children, so the outer packaging can include ingredient and health information. Once opened, the secondary packaging can be aimed at children.

But he does not believe there is an ethical imperative to package snack foods in a less attractive way. ‘I don’t think there is a problem with having indulgent brands. It is the duty of other brands to become more alluring – we should package carrots better,’ he explains.

Duckworth says it would be wrong for pack designers to misinterpret the nature of a product to make it look more healthy. ‘Trying to change an artificial product into a healthy looking one like Sunny Delight is pointless. Packaging has to be true to the brand,’ he says.

Sunny Delight was originally merchandised by Procter & Gamble in chiller cabinets, giving the impression it was a healthy, natural drink like orange juice. Sales soared initially, but when it emerged that it contained little real fruit, sales fell and P&G eventually sold it off.

Pack design will play a crucial role in the marketing of snack foods, especially when TV advertising and other forms of marketing are curtailed. Design will then carry the brunt of providing solutions to a growing health crisis, and be subjected to the same intense scrutiny.
